Qatar's Energy Minister said on Thursday that the attacks on the country's energy installations will reduce the export capacity of liquefied natural gas (LNG) by 17 per cent, leading to an estimated annual revenue loss of USD 20 billion, news agency AFP reported.

"The damage sustained by the LNG facilities will take between three to five years to repair. The impact is on China, South Korea, Italy and Belgium," said Energy Minister Saad Sherida Al-Kaabi in a statement.
